record locks established against a file in the filesystem by each node in the cluster
are invisible to all other nodes in the same cluster.
Before using this option, ensure that either all processes performing record lock
operations in the affected filesystem are running on the same single node in the
cluster, or that the necessary mutual exclusion semantics for record locking have
been implemented in some other way. Note that this option affects record locks
obtained by the Linux fcntl system call. The Linux flock system call is not af-
fected.

Optimize file access for database data files.
Mount snapshots
Snapshots can be mounted in the same manner as filesystems. Before mounting a
snapshot, you will need to determine which psd or psv volume contains the snapshot.
The following command reports the volumes used by the existing snapshots.
mx fs status ––snapshots
When you have determined the correct volume, use mx fs mount <volume> to
mount the snapshot.
recreate—Recreate a PSFS filesystem
mx fs recreate [optional-arguments] <storageDevice>
The optional arguments are the same as mx fs create.
showcreateopt—Display information about available volumes
mx fs showcreateopt
status—Display status information
mx fs status [--mounted|--unmounted] [--persistent] [--verbose]
[--standard|--snapshots]
The --mounted argument displays only mounted filesystems; --unmounted displays
only unmounted filesystems. The --persistent argument displays only those
filesystems with persistent mounts. The --verbose option displays the FS type
(always PSFS), the size of the filesystem in KB, and the UUID of the parent disk. The
--standard argument shows only standard filesystems; the --snapshots argument
shows only snapshots.
unmount—Unmount a filesystem
mx fs unmount [--persistent] [--active] <filesystem> ALL_SERVERS|<server> ...
